The descendants of a fourth Earth colony ship, Destiny, successfully establish a foothold in unoccupied space. Naiad, the home world, is a frozen ball, but the colonists persevere and expand through wormholes to remote systems. Navigating the time-space anomalies requires Axis-ships. The expensive vessels are constructed by corporations, and remote worlds are claimed by the companies for their valuable ores and gases.

An explorer tug captain, Alex Racine detects a damaged alien craft drifting into the system. Recognizing a once-in-a-lifetime opportunity to make first contact, Alex pulls off a daring maneuver to latch on to the derelict. Alex discovers the ship was attacked by an unknown craft, the first of its kind ever encountered. The mysterious silver ship's attack was both instant and deadly.

Jason Burke was a man hiding from himself in a small cabin high in the American Rocky Mountains when his simple, quiet life was shattered one night by what he first assumed was an aviation mishap. But when he investigates the crash, what he finds will yank him out of his self-imposed exile and thrust him into a world he could have never imagined.

Captain Jessie Cinders faces a hazardous choice. The murderer of the governor's nephew stands before him. But, the frightened teenager, Aurelia Garmenti, doesn't resemble the commandant's description of the vicious, hardened killer his security forces seek.

Aliens exist...and, as it turns out, most of them aren’t that friendly. Jacob Brown wasn’t even born yet the first time they attacked Earth. He was only 14 the second time it happened. When Earth finally came together and fielded its first spaceborne military, Jacob didn’t hesitate to volunteer. Serving aboard a mighty starship, he’d be able to defend his planet - and his family - when, inevitably, they came again.
